$An object P is focused by a microscope M. A glass slab of thickness 2.1 cm is introduced between P a Question No. 17- An object P is focused by a microscope M. A glass slab of thickness 2.1 cm is introduced between P and M. If the refractive index of the slab is 1.5, by what distance should the microscope be shifted to focus the object again ? | physics Class 12 chapter- Geometrical Optics solution by ujwal Kumar physics master | physics master academy is best coaching for all physics students. best physics teacher of neet, JEE-Mains in delhi Download our app for android and ios http://on-app.in/app/home?orgCode=vdtxq$

$A Youngs double slit setup is illuminated with monochromatic light. If the intensity of light pass 31(a)- A Youngs double slit setup is illuminated with monochromatic light. If the intensity of light passing through one of the slits is reduced, explain the changes that can be seen in the appearance of the bright and dark fringes?(b)(i)- A single slit diffraction setup is illuminated with green light of wavelength 500 nm. If the width of the slit is 1 mm and the screen is 2 m away from the slits, calculate the width of the central maximum. (ii)- What will happen to the width of the central maximum, if the green light is replaced with the red light?
